' GRAIN-BIN.

To all whbm'it may concern:

Be it known that I, ALBnRr N. EATON, av

citizen of the United States, residing at Y Omaha, in the county of Douglas and State of Nebraska, have invented certain new and useful lmproveinents 1n which the following is a specification.

This inventionirelates to improvements in portable grain bins, and has for its object the provision of a bin ofthis class which may be economically constructed of metallic sheets for housing the grain, and vwhich will be convenient in use for filling and for removal of grain. r v

The invention has reference to certain novel featuresw-hereby material and labor may be economized toreduce the cost of con.- struction, and incl-udes the employment of convenient foldable chutes in connection with exit ports, with closing and securing means therefor, located a-t different altitudes upon the wall of the tank.

With these and other objects in view the invention presents a novel combination and arrangement of parts, as described herein, pointed out in the appended claims, and as illustrated by the accompanying drawing, wherein,-

Figure 1 is a vertical sideview of a -grain tank, partly in section, constructed in accordance with my invention. Fig. 2 is a plan view of the tank body shown in Fig. 4,

.parts being broken away. Fig. 3 1s a view of thetank in longitudinal section, broken lines showing the position of the chuteswhen lowered. Fig. 4 is a front View of the tank, the roof or cover being removed.

For a more particular description, Figs. 1 and 2 show a cylindrical casing l with a circular bottom 2 'secured transversely thereon to form a container or grain bin 3, casing'l having a conical roof or cover l secured thereon. The bin may have any suitable dimensions, and since it is often used in the grain fields, itis constructed lin `amanner7 as will be explained, so that its contents may be protected from the weather.' Casing 1 may be readily formed by using a plurality of or supports indicated, respectively, at 8 and 9; they-are bent circular-ly, their vertical Grain-Bins, ofl

17 which is seated upon the horizontal flan-ge' 13 of support 8, and by means 'of rivets 18 driven through this peripheral flange and seated in apertures 14, the roof may be secured upon the casing.

The bottom is formed by use of a circular metallic plate 19 having a diameter less than that of the casing, and is seated upon the horizontal flange 15 of qsupport 9, and, by means of rivets 20 driven through plate 19 'and seated in apertures 1G, it may be secured to Aprovide the bottom 2.

s thus described the construction is simple and'is accompanied with slight comparative expense to provide abottom vplate elevated above the lower terminal of the casing,

and by said casing housed from the weather.

Peripheral flange 17 extends outwardly of the horizontal llange 13 of support 8, and is,

down-turned at its terminal to form the annular bead or ridge 21, these features being for the purpose of causing rain or moisture to be conveyed and deposited outwardly of the casing and outwardly of any part of flange 13. The vertical, metallic reinforcing bars or strips 7 are apertured at intervals, as indicated at- 22, and by use of rivets 23, seated in these apertures and driven through and near the edges of sheets 5, these sheets-fare securely held together toadequately resist the outward strain occasioned by the grain, and to form the-complete casing l. y

At 24 is indicated a receiving port or manhole disposedv intermediate the peripheral flange and apex of the roof, preferably having a circulzrrg'wertical Wall 25 secured upon vthe roof, preferably by'v soldering it thereon,

andv provided-,with a removable cover26. -i 'F or the purpose of providing' exit ports #which may have convenient closing means protected-.from the weather, and f or providing'means for conveying the grain after'it is thrown frm Vthe ports, said means to also -operate 'as housing-plates to protectthe ortopenings, certain de'vices found to be o advantage, Vwill now be explained.

Exteriorly upon casing 1 are 4 jacent, lvertical bracket-bars or a pair lof angle ironsV 26, of a length, substantially equal to that of the casing, and 'each having a flange 27 disposed parallel with 'the surface of the casing, transversely considered,V

in directions opposed to each other, and anges28-thereof projecting` outwardly of the casing and disposed parallel, for convenient supports for the. pivotal mounting., therebetween, of the conveying chutes -hereafter described. 4 l

-. Flanges 28' are provided .with apertures 48 near their bottoms, with apertures '49 near y their upper ends, aiidintermediate' these lowerand upper apertures they are provided with downwardly and' outwardlv inclined slots 50, for uses presently explained.

, 'Flanges 27 are provided withapertures 23 formed at longitudinal. intervals th3rein,f

and, by. means of rivets 30'driven through the vertical wall of they casing and seated in.

apertures 29, the bracket-bars may be secured to the casing. j.

Bracket-bars 26 are disposed a suiiicient distance apart to provide ports or -openings therebetween, these being formedin the casing at different altitudes and of any desired y number required for conveniently unloading the grain. j tend to weaken v,the casing, the bracket-bars operate, to reinforce the wall adjacent these openings, so that thestrenothjof the. casing vis not impaired. Intermediate the 'top'and bottom of and between bracketfbars 26 and at different altitudes thereon, are provided j ports 31 and 32, for passage ways of grain.

They are provided by forming'circularopeii'- ings 33 in the casing, and employing collars 34 having transverse flanges 35 disposed flush with openings 33 and secured, prefer' and' extending outwardly from the casing,

'disks 36 having rims or flanges 40 for seatings within the transverse flanges 35 of collars34; and as described vthe disks may be operativelymounted and secured to eifectw' ally close the ports by'manually turningthe latch to engage the catches, and for removal of grain, covers 36 or either of them may be readily removed Apron'or .partition 41 is providedl and secured-interiorly of the casing adjacent .the lowerv port 32, and an operator, when inside the-bin may shovel orthrow the grain outdisposed ad-i 'l .-is` first removed lVhile the openings thus formedl ward through portsv31'and32fand when. l

the grain is` nearly emptied, apron 41 is convenient for lodgment thereon of grain or sjveepings'thrownthereon, and is used for thispurpose.

Chutes 42 and veyiiig the grain outwardly fromv the respective ports 31 and 32 when unloading 43 iare provided for con the bin, and are` constructed. of suitablelengths for this pur ose. They are preferably lformed withV atl bottoms 44 having upset 4or transverse sides45 formed longitudinally convergent from their ,bases-46 to theirfree ends'.v The-chutes are mounted adjacent ports 31 `and 32 'and between flanges 28 of bracket-bars 26 this mounting vbeing pivotall by means `of rivets ,47 secured in the wider ends of sides 45,1 vlherivets 47 of chute 43 are'seated iii apertures 48'of flanges 28, whereby this chute," may have swinging movements of substantially degrees downward from the vertical wall ofthe casing.

Rivets 47 of chute 42 are seated in inclined' slots.50, and thereby this chute may have swinging movements similar to the move'- ments ofchute 43.

In operation, whenu'nloadiiig the '.bin, one I of the 'chutes isV used, being first swung downward to convey grain thereon, when thrown out of the port and in this operation, the disk or coverv ofthe port, of course,

in the manner already described.

. It is importantl to preserve the contents of the bin froml rain or moisture and'chutes 42y and 43 operate for this purpose since they i' effectually protect the vports when swung."

upward to a closed position. w The chutes as described l have downward swinging movements to dispose their free ends at a somewhat lower.

altitude than the respective ports, at the sides of which they are mounted, and at this time are sustained in this position by a conltact of their bases upon the surface ofthe casing; they may have upward swinging movements to befolded or held by conven-y ient means hereafter mentioned.

The upper chute .may be held in a closed position after it has been swung upward, Aby means of locking pins 51 passing within apertures 49; and at this time its free end.

will be disposed inwardly of flange 17 of roof or cover 4, aiid its base A46 will project outwardly of the disk; also its sides will be are adapted tol I dis osed outwardly of the sides of the disk i an port which it overhangs.

When the chutes are folded, the lower chute is held in a closed position since its free end 52 is 'conned upon the inner side of the base of chute l42; the base of' this chute, at this time projects outwardly of its adjacent disk and overhangs the port, in all respects similar to the base of the upper chute; andit will be seen that rain falling p while engaged within'inclined slots 50 of the parallel bracket-bars.

While I have shown an integral sheet 19 to rovide a bottom plate I do not limit myselr to such integral construction. The number of sheets required-'for constructing the wall of the casing will vary according to the diameter or size desired; and it is apparent .that the number of ports and chutes may be increased without ldeparting from the scope ofthe invention.

Having fully described my invention, what I claim and desire to secure by Letters Pat'- ent is,-

l. In combination, a bin of the class described, comprising avertically disposed, cylindrical casing provided with adjacently disposed, upright bracket-bars, and with openings formed therein intermediate the bracket-bars; circular angle irons, each having a flange disposed vertically upon the casing and circuinscribing one of said openings; closure plates each having a transverse flange, said closure plates adapted to have seatin'gs to cov'er the openings of the casing, said transverse flanges registering with thehorizontal .flanges of said circular angle irons; longitudinal conveying upper and lower chutes having their bases pivotally mounted upon said bracket-bars adjacent said openings and adapted to haveupward swinging movements to dispose 'their upper ends adjacent said casing between Asaid bracketbars, the base of an upper chute overhanging the terminal of a loWer..chute.
